L-shaped coprime array structures for DOA estimation [PDF]
, 2020 This paper proposes a new sparse array geometry for 2-D (azimuth and elevation) directionof-arrival (DOA) estimation based on coprime sampling. The proposed array structure is L-shaped coprime array (LCA) whose each portion is one dimensional coprime ...

SOME PROPERTIES ON COPRIME GRAPH OF GENERALIZED QUATERNION GROUPS [PDF]
, 2023 A coprime graph is a representation of finite groups on graphs by defining the vertex graph as an element in a group and two vertices adjacent to each other's if and only if the order of the two elements is coprime.

Coprime Factorization with J All-Pass Denominator: The Noncanonical Case [PDF]
, 1999 Given an arbitrary rational matrix G, we are interested to construct the class of coprime factorizations of G with J-all pass denominators of McMillan degree as small as possible.

Tensor-based approach to the co-prime planar array signal processing
Tongxin xuebao, 2020 For the co-prime planar array (CPPA) consisting of two sparse uniform rectangular array (URA),a new processing method based on tensor algebra was proposed to enhance the degrees of freedom (DoF).By dividing each URA into some overlapping subarrays,the ...

Generalized coprime array configurations
, 2014 A coprime array consists of two uniform linear subarrays that con-struct an effective difference co-array with certain desirable char-acteristics. In this paper, we propose a generalized coprime array concept through the compression of the interelement ...

Improved 2D Coprime Array Structure with the Difference and Sum Coarray Concept
, 2020 Recently, the difference and sum (diff-sum) coarray has attracted much attention in one-dimensional direction-of-arrival estimation for its high degrees-of-freedom (DOFs).

On the detection of knots by their traces in high dimensions
Proceedings of the London Mathematical Society, Volume 133, Issue 4, October 2026.Abstract For every n⩾4$n\geqslant 4$, we demonstrate the existence of non‐isotopic, smooth (n−2)$(n-2)$‐knots in Sn$S^n$ with diffeomorphic traces. We give two proofs: the first by generalising the RBG link construction to all dimensions, and the second as an application of work of Plotnick.
